NASA senior scientist Amy Simon joined CBS News to discuss the purpose ...

The goal of 3-D printing is to take this capability to microgravity for use on the International Space Station. In space, whatever astronauts have available on orbit is what they have to use -- but just like on Earth, parts break or get lost. When that happens, there's a wait for replacement parts, ...

Astronaut Ron Garant answers the question: So we have routine travel between Earth and its nearest neighbor. By doing that that would open up the entire solar system. That enables us to use the resources that are on the moon. It enables us to launch in a much lower gravity field than Earth. It opens

When wolves were reintroduced to Yellowstone National Park in the United States after being absent nearly 70 years, the most remarkable "trophic cascade" occurred. What is a trophic cascade and how exactly do wolves change rivers? George Monbiot explains in this movie remix.

This is my "Change the World" project for my school environmental science class.

Mars is a cold and barren desert today, but scientists think that in the ancient past it was warm and wet. The loss of the early Martian atmosphere may have led to this dramatic change, and one of the prime suspects is the solar wind. Unlike Earth, Mars lacks a global magnetic field to deflect the s

"Our gun laws will change," Ardern promised in a news conference on Saturday morning, local time. She said the shooter had five guns, two s...

NASA May Have Found the First Planet in Another Galaxy. “We know we are making an exciting and bold claim so we expect that other astronomers will look at it very carefully,” study co-author Julia Berndtsson of Princeton University said in a statement. “We think we have a strong argument, and this

The spacecraft crashed into an asteroid the size of the Washington Monument. NASA’s DART spacecraft intentionally collided with an asteroid on Monday evening, in an attempt to alter the space rock’s trajectory. The mission tested technology that could help defend Earth against potential future aster

Penn was built on the concept of innovation. “If it’s new, novel and holds promise to change the world,” says President Amy Gutmann, “you’ll find it at Penn.”
